HYDROGARBON-BURNEB.

Specification of Letters Patent.

Application filed February 20, 1920. Serial No. 360,138.

To all whom it may concern:

Be it known that LALoNzo WV. GEARHART, a citizen of the United States, and resident of Fresno, in the county of Fresno and the State of California, have invented a new and useful Improvement in Hydrocarbon Burners, of which the following isa specification.

My invention relates to a hydrocarbon burner for gasifying and burning low grade fuel oils for use in stoves, furnaces and like places where it is desired to create heat. This invention is an improvement on that certain hydrocarbon burner for which a Patent No. 860,460 was issued to me 'onJuly 16.1907.

The objects of the invention described herein is to provide a burner having a frame support arranged so that a brick wall can readily be built around it, having an oil feed which will not readily clog up when cleaning carbon from the burner, to produce a box for the burning fuel which will .not permit the oil to waste into the ash pan,

and which will direct the flame so that the upper portion of the burner will not become (super heated. Other objects have been ac complished which will hereinafter appear. In the drawing accompanying this specification and'hereby made a part hereof, Fig;

ure 1 is an isometric view of the burner complete. Fig. 2 shows a pipe draft flue.

. Fig. 3 is a frame support for the front wall of the burner. Fig. .4 is a sectional view of the front plate. Fig. 5 is a sectional view of the burner installed with baffling wall sides 2 and'Q aback end 3 of-approximatelv the same height as the sides. and a bottom. or burning plate 4;. The sides andback are made the same height "to prevent the fuel from overflowing- The plane of the end 3 and the plane of the bottom 4: adjacent thereto forms an acute angle. The

portion 4 of the burning plate opposite to the end 3 flares upward, preferablyterminating with any upward curve". Directly above portion eis a flue plate ,5 which extends from the side 2 to side 2, dropping downward in an oblique direction, and terminating at the lower end with aportion a eat-ending parallel with bottom 4. 15* 1a the extreme upper portion of the flue plate 5 which appears as a bar on the top of sides 2 and 2, and connecting said sides together. The formation described leaves an opening between the flaring portion P and the flue plate 5 which can be termed the lower draft flue B. 7 is a fuel or oil supply pipe which should pass through the burning plate within the flue B; Fuel pipe 7 should enter the flue through a vertical hole 7 In my former patent referred to the fuel pipe was placed at a slight angle from a horizontal line and cleaning theburning plate by scraping, the fuel pipe was frequently Patented Oct. 19, 1 920.

clogged up whereas by making the said opening vertical the scrapercan be dragged over it without pulling much carbon therein.

6 and 6 are parallel flanges on sides 2 and 2 forming an oblique slideway 6 directly back of bar 5. C is a front support constructed with two uprights 9 and 9 having against the support C and toward the back of the burner. This form is substituted. for the flanges in my former patent which were bolted to the walls of the stove,

as it has been found advisable to have the front wall leaning in this manner and to' 1 have the entire I construction of more rigid material than the stove walls are usually made of, and to have the front removable.

Further, in bricking a burner in a furnace the top'plate 8 forms abase on which brick can "rest. hole 10 through the approximate center into which a draft pipe E is fitted. This pipe should be easily removable and should nor-- 'mally remain in place when adjusted. To

Theffront plate D has anoblique accomplish this I have formed a reduced portion 11 which easilypasses through the hole 10, and have constructed a stop 12 on." the top end of the pipe so when assembled the reduced end can be stuck through hole 10 and gravity will-hold the lower end down so that stop 12 on the upper end will engage the wall and prevent the pipe from slipping out. In my former construction the curwas directed so a back draft was created and the pipe conducting the draft was frequentlyunduly heated. In the present invention I have formed the upper draft pipe rent ofair passing through the upper draft i on the two sides of the burner, extending, to

the top, designated on'the drawing as H and H and having a back baffling wall F which is constructed to angle upward and outward, and to the same height as the side walls. At each corner on the top of the fire box I have placed an uprght post 13, 13",

13 and 13 which support a baffling plate or heat spreader Gr.

F is a bafile wall which directs the currents of heated air from the upper and ll)ower drafts upward as it leaves the mixing ox. I I

In using this burner small -quantityof oil is admitted to the burning plate, and

ignited in the usual manner, thus heating the plate, when the oil can be turned on in larger quantities and the heated plate and oxygen from the air drafts will form a hot fire and heat the stove or furnace readily.

I claim as newand ask for Letters Patent; V v

1. In a burner of the character described the combination of a burner plate, a frame around the burning plate, a front portion extending upward above the frame, a fuel ,lead, a lower draft disposed at the front 1 end of the burner and an upper draft composed of a straight pipe extendingthrough the front wall obliquely and pointing toward the approximate center of the burner plate, substantially as described.

2. In a hydrocarbon burner, the combination of a noncombustible box having a hottom, parallel vertical sides, a rear end of the same approximate height disposed so the upper portion leans inwardly, a baflle wall above the rear end constructed toelean outwardly. a front end to said box having an upper draft and a lower draft, the line of said drafts being adapted to meet at an acute angle at the approximate center of the bottom of the box and a fuel feed opening in the path of the lower draft, substantially as described. g

3. In a hydrocarbon burner the combination of a noncombustible box having an open top, a baffle wall at one end extending upward andoutward from a perpendicular line, and a" lower and an upper draft opening adapted to direct'currents of air so they will meet on the upper surface of the bottom of the box at the approximate center thereof, said currents meeting at an acute angle, and a fuel intake opening consisting of a vertical hole through the bottom of the box in the line of the lower draft.

projecting obliquely through the extended end, and adapted to dire-l t a current-of air obliquely to the approximate center of the bottom of. the box substantially as described. Y r

5. In a hydrocarbon burner in combination with a fire box closed on four sides, having an opening for gas and heated air on the upper side' thereof, of a noncombustible auxiliary box having an open top, a baffle wall at the back end extending beyond the top of the auxiliary box, two openings in the wall opposite the bafiie plate having draft leads to the interior of the auxiliary box, saiddraft leads being adapted to direct one current of air to pass along the bottom of the auxiliary box toward. thecenter of V the bottom of the auxiliary. box, and .a fuel lead in thepath of the lower draft. 7 6. In a hydrocarbon burner, the combination of a noncombustible box having a bottom, parallel vertical sides, a rearend of the same approximate height disposed so the upper portion leans inwardly, abafile wall above therear end constructed to lean. outwardly. a front end to said box having an upper draft and a lower draft, together with v a baffle plate supported so itcovers the box with openings between the top wallsbf the I boxrand the baffle plate, substantially asde:

7.- In a hydrocarbon burner 1n combinat1on. afire box lnclosed on four sides and of the fire ,boxtoward the end having the baflie'walL- one current to pass from the end opposite the bafile wall obliquely toward the center ofithe bottom of the fire box, and a spaced horizontal partition extending from one side to the other of the fire box between V the upper and lower drafts, a fuel lead open- .in 'in the path of the lower draft substantially as described. r

8. In a-hydrocarbonburner. in, combination, a fire box inclosed on four sides, a.
